Due to the long-term use of the old version 5.5 and the mariadb branch version on Windows devices. 5.7 is rarely used, so occasionally it takes a long time to install 5.7 to test some troubles. Download the record here for easy viewing later.

Create configuration
As of MySQL version 5.7.18, the configuration file my-default.ini will no longer be included, so copying the configuration file will not start.
Taken from: https://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html
Since then, a handwritten configuration file is performed.
[client]
port=3306
socket=/tmp/mysql.sock
[mysqld]
port=3306
socket=/tmp/mysql.sock
key_buffer_size=16M
max_allowed_packet=8M
[mysqldump]

Add base and data directories:
[client]
port=3306
socket=/tmp/mysql.sock
[mysqld]
port=3306
socket=/tmp/mysql.sock
key_buffer_size=16M
max_allowed_packet=8M
basedir="D:/tools/MySQL/mysql5.7.20"
datadir="D:/tools/MySQL/mysql5.7.20/data"

For other configurations, you can refer to the official documentation to add them later.

Run CMD with administrator privileges
>d:
>cd "D:/tools/MySQL/mysql5.7.20/bin"
# 以下命令二选一。
# 其一，初始化数据库目录，生成随机MySQL密码至日志文件中。
# 其二，初始化数据库目录，生成（空）密码。
>mysqld --initialize
>mysqld --initialize-insecureafter execution to
Search for the keyword keyword in the ./data/DESKTOP-****.err file.
